Non-stick performance of polymethylsilsesquioxane thin films synthesized by sol–gel spray coating

The non-stick properties of polymethylsilsesquioxane (PMSQ) sol-gel films fabricated via spray coating were investigated in this study. A high non-stick performance was achieved by preparing sols under strongly acidic conditions. Infrared absorption spectroscopy analyses suggested that these conditions promoted the formation of highly symmetric Si-O-Si structures, which contributed to the enhanced non-stick behavior. The PMSQ films proposed in this study are transparent and fluorine-free, rendering them suitable for applications such as cooktops.
